2021-11-09Split route data structure to storage (ro) / manipulation (rw) structures.Maria Matejka
Routes are now allocated only when they are just to be inserted to the table. Updating a route needs a locally allocated route structure. Ownership of the attributes is also now not transfered from protocols to tables and vice versa but just borrowed which should be easier to handle in a multithreaded environment.

2021-10-13Route: moved rte_src pointer from rta to rteMaria Matejka
It is an auxiliary key in the routing table, not a route attribute.

2021-10-13RIP fixup + dropping the tmp_attrs mechanism as obsoleteMaria Matejka
2021-10-13Dropping the RTS_DUMMY temporary route storage.Maria Matejka
Kernel route sync is done by other ways now and this code is not used currently.

2021-10-13Export table: Delay freeing of old stored route.Maria Matejka
This is needed to provide the protocols the full old route after filters when export table is enabled.

2021-10-13IGP metric getter refactoring to protocol callbackMaria Matejka
Direct protocol hooks for IGP metric inside nest/rt-table.c make the protocol API unnecessarily complex. Instead, we use a proper callback.
2021-09-10Nest: Clean up main channel handlingOndrej Zajicek (work)
Remove assumption that main channel is the only channel.

Remove assumption that main channel is the only channel.
2021-06-14Nest: Fix export of tmpattrs through pipesOndrej Zajicek (work)
Pipes copy the original rte with old values, so they require rte to be exported with stored tmpattrs. Other protocols access stored attributes using eattr list, so they require rte to be exported with expanded tmpattrs. This is temporary hack, we plan to remove whoe tmpattr mechanism. Thanks to Paul Donohue for the bugreport.
2021-06-14Revert "Nest: Fix export of tmpattrs through pipes"Ondrej Zajicek (work)
This reverts commit f8e273b5e7a3c721f4a30cf27a0b4fe54602e83f.
2021-06-14Nest: Fix export of tmpattrs through pipesOndrej Zajicek (work)
In most cases of export there is no need to store back temporary attributes to rte, as receivers (protocols) access eattr list anyway. But pipe copies the original rte with old values, so we should store tmpattrs also during export. Thanks to Paul Donohue for the bugreport.
2021-06-09Nest: Allow both 'password' and 'key' keywords for authentication keysOndrej Zajicek (work)
2021-06-06Nest: Fix password list parsing codeOndrej Zajicek (work)
One of previous patches broke password list parsing code, fix that.
2021-06-06Nest: Allow MAC algorithms to specify min/max key lengthToke Høiland-Jørgensen
Add min/max key length fields to the MAC algorithm description and validate configured keys before they are used.
2021-06-06Nest: Allow specifying security keys as hex bytes as well as stringsToke Høiland-Jørgensen
Add support for specifying a password in hexadecimal format, The result is the same whether a password is specified as a quoted string or a hex-encoded byte string, this just makes it more convenient to input high-entropy byte strings as MAC keys.
2021-06-06Lib: Add Blake2s and Blake2b hash functionsToke Høiland-Jørgensen
The Babel MAC authentication RFC recommends implementing Blake2s as one of the supported algorithms. In order to achieve do this, add the blake2b and blake2s hash functions for MAC authentication. The hashing function implementations are the reference implementations from blake2.net. The Blake2 algorithms allow specifying an arbitrary output size, and the Babel MAC spec says to implement Blake2s with 128-bit output. To satisfy this, we add two different variants of each of the algorithms, one using the default size (256 bits for Blake2s, 512 bits for Blake2b), and one using half the default output size. Update to BIRD coding style done by committer.
2021-04-19Internal route tables have a reduced cleanup routineMaria Matejka
This fixes an internal table cleanup bug introduced in ff397df7edcbe7a8abca5b419729b9c64c063847.
2021-03-30Allocation of ea_list in one contiguous memory blockMaria Matejka
This saves some bytes of memory for complex ea's.
2021-03-30Routing table is now a resource allocated from its own poolMaria Matejka
This also fixes memory leaks from import/export tables being never cleaned up and freed.
2021-03-30Routing tables list iteration should use explicit node struct positionMaria Matejka
2021-03-17Minor fixes for restricted buildsOndrej Zajicek (work)
2021-03-16Pipe: Propagate debug flags from protocol to channelsOndrej Zajicek (work)
Pipe channels are kind-of implicit, so setting protocol debug flags should also set pipe debug flags.
2021-03-12Rate-limit scheduling of work-eventsOndrej Zajicek (work)
In general, events are code handling some some condition, which is scheduled when such condition happened and executed independently from I/O loop. Work-events are a subgroup of events that are scheduled repeatedly until some (often significant) work is done (e.g. feeding routes to protocol). All scheduled events are executed during each I/O loop iteration. Separate work-events from regular events to a separate queue and rate limit their execution to a fixed number per I/O loop iteration. That should prevent excess latency when many work-events are scheduled at one time (e.g. simultaneous reload of many BGP sessions).
2021-03-09Nest: No automatic ROA reload on non-reloadable channelsOndrej Zajicek (work)
2021-02-12Nest: Add option to control automatic RPKI reloadOndrej Zajicek (work)
Also, no automatic reload for BGP channels without import/export table.
2021-02-10BGP: Add support for BGP hostname capabilityVincent Bernat
This is an implementation of draft-walton-bgp-hostname-capability-02. It is implemented since quite some time for FRR and in datacenter, this gives a nice output to avoid using IP addresses. It is disabled by default. The hostname is retrieved from uname(2) and can be overriden with "hostname" option. The domain name is never set nor displayed. Minor changes by committer.
2021-02-10Nest: Automatic channel reloads based on RPKI changesOndrej Zajicek (work)
If there are roa_check() calls in channel filters, then the channel subscribes to ROA table notifications, which are sent when ROA tables are updated (subject to settle time) and trigger channel reload or refeed.
2021-02-07Filter: Recursive filter iteration codeOndrej Zajicek (work)
Add macros for recursive filter iteration that allows to examine all instructions reachable from a filter.
2021-01-06Nest: remove last_tx_filter_changeOndrej Zajicek (work)
No longer needed after redesign of export handling.
2020-12-29Nest: Read Babel metric as IGP metricJames Lu
(Minor syntactic changes by committer)
2020-12-07Nest: Per-channel debug flagsOndrej Zajicek (work)
The patch add support for per-channel debug flags, currently just 'states', 'routes', and 'filters'. Flag 'states' is used for channel state changes, remaining two for routes passed through the channel. The per-protocol debug flags 'routes'/'filters' still enable reporting of routes for all channels, to keep existing behavior. The patch causes minor changes in some log messages.
2020-11-24Minor cleanups with cfg_allocz()Ondrej Zajicek (work)
Also fixes some more failed asserts due to add_tail().
2020-11-24Fix some failed asserts due to add_tail()Ondrej Zajicek (work)
When config structures are copied due to template application, we need to reset list node structure before calling add_tail(). Thanks to Mikael Magnusson for patches.
